Abstract/Contents:"Kikuyugrass [Cenchrus clandestinus (Hochst. ex Chiov.) Morrone (= Pennisetum clandestinum Hochst. ex Chiov.)] is a warm-season species native to Africa. It was introduced into the United States at the beginning of XX century for soil erosion control and quickly spread throughout coastal California and Hawaii. With proper maintenance, kikuyugrass has become a valuable species for golf course fairways, athletic fields and lawns. Increasing popularity of kikuyugrass as a turfgrass created the need for improved genotypes. The process of breeding of kikuyugrass at the University of California, Riverside was started in late 1980's, but the project was ceased after few years. The program has been relaunched in 2016 by creating a new germplasm collection. So far more than 200 genotypes of kikuyugrass from various areas of California have been collected and are under evaluation. Kikuyugrass is listed on the Federal Noxious Weeds List and import of its germplasm is restricted, however a diversity study performed after assembling the collection revealed sufficient diversity among this species in California. After initial screening, crosses between genetically distant accessions with desirable characteristics were performed. That generated 280 hybrids, planted in 2019 and evaluated through 2020 and 2021, which resulted in selection of 40 hybrids to be planted in test plots in 2021. Despite moderate level of genetic diversity, new hybrids exhibit wide range of variation in some of the evaluated traits, such as texture and flowering intensity. Less variation was observed for winter color retention, which in general is better than in other warm-season turfgrass species. In the next phase superior genotypes and hybrids will be tested in replicated trials for tolerance to shade, drought and disease, and other traits. Meanwhile, new hybrids are being produced and will undergo evaluation and selection."
